[0026] The following is a further detailed description of this application with reference to the accompanying drawings and specific implementations:

[0027] like Figure 1-Figure 7The illustrated hanging system is suitable for the construction of a circular main structure and includes a V-shaped connecting crossbar 1, a horizontal hanging frame protective mesh 2, a hanging frame upright 3, and a vertical safety mesh 4. The V-shaped connecting crossbar 1 includes two horizontal steel sections 11, a steel inner support 12, a U-shaped buckle 13, a tension bolt 14, a tension nut 15, and a steel washer 17. One end of the two horizontal steel sections 11 is close together, and the other end is separated to form a V-shaped structure; a steel inner support 12 is provided between the two horizontal steel sections 11, and the tension bolt 14 tension-connects the two horizontal steel sections 11. Steel washers 17 are welded to the ends of the two horizontal steel sections 11, and the welding point 16 is located between the steel washers 17 and the horizontal steel sections 11. The steel inner support 12 can adopt a telescopic structure or can be made on the construction site. The angle α between the V-shaped connecting crossbar 1 and the two horizontal steel sections 11 of each V-shaped connecting crossbar 1 is determined according to the size of the circular main structure.

[0028] The horizontal hanging frame protective mesh 2 includes a V-shaped protective mesh 21, a channel protection mesh 22, a connecting screw 23, a protective flap mesh 24, a first hook ring 25, a hanging chain 26, and a second hook ring 27. The V-shaped protective mesh 21 is installed on the V-shaped connecting crossbar 1. The channel protection mesh 22 and the protective flap mesh 24 are both rectangular. The channel protection mesh 22 is connected to the V-shaped protective mesh 21 on both sides. The end of the channel protection mesh 22 closest to the circular main structure is connected to the protective flap mesh 24 via a connecting screw 23, while the end away from the circular main structure is connected to the vertical safety mesh 4. The channel protection mesh 22 and the protective flap mesh 24 are also connected by a first hook ring 25, a hanging chain 26, and a second hook ring 27. The horizontal angle of the protective flap mesh 24 can be adjusted by controlling the length of the hanging chain 26 to ensure that the horizontal angle of the protective flap mesh 24 meets the construction requirements. The channel protection mesh 22 enables construction workers to pass through, and the protection flap mesh 24 plays a role in protecting personnel while ensuring that scattered objects are prevented from falling.

[0029] According to the radius R of the circular main structure and the width W of the preset rectangular channel protection mesh 22, the angle α=360 / (2πR / W) degrees between the two horizontal steel sections 11 of the V-shaped connecting crossbar 1 is calculated, and the installation is performed accurately according to the calculated results.

[0030] During the actual installation process, first secure the hanger uprights 3 to the construction location according to the design requirements. Hanger uprights 3 primarily support vertical forces. Next, connect the V-shaped connecting crossbars 1 to the hanger uprights 3 using the upright bolts 32 and nuts 33. Next, install the horizontal hanger protective mesh 2 onto the V-shaped connecting crossbars 1 and hanger uprights 3, ensuring a secure connection. Finally, install the vertical safety mesh 4, forming a complete protective system with the entire hanger assembly.

[0031] During the entire construction process, the various components of the hanger device must be regularly inspected to ensure their stability and safety. If any components are found to be damaged or loose, they must be repaired or replaced in a timely manner.

[0032] The above are only preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be pointed out that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
